A Novel PSNR-B Approach for Evaluating the Quality of De-blocked Images
Trinadh Tadala · IOSR Journal of Computer Engineering · 2012
JPEG Compression is the most prevalent technique or method for images codecs.But it suffers from blocking artifacts.In this paper a comparison of the perceptual quality of deblocked images based on various quality assessments metric is done.A proposed PSNR including blocking effect factor was used instead of PSNR.Another quality assessment metric SSIM was used which produces results largely in accordance with PSNR-B.We show the simulation results, which prove PSNR-B produces objective judgments.The efficiency of deblocking algorithms was studied.
